DETACHABLE SHOE-HEEL PAD AND FASTENING DEVICE THEREFOR.

Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed April 10, 1919. Serial No. 288,972.

To all whom it may concern.

Be it known that we, BONNIE WALTERS and LEW ARNTz, citizens of the United States, and residents of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Detachable Shoe-Heel Pad and Fastening Device Therefor, of which the following is a specification.

The object of our invention is to provide a detachable shoe heel pad of simple, durable and inexpensive construction.

Another object is to provide a detachable heel pad whereby a new one may be substituted without the necessity of having shoes in a shoe repair shop. I

Still a further object is to provide a detachable heel pad having a plate firmly secured to the fixed shoe heel 11, and means upon said plate for holding the detachable heel pad to the plate.

Still a further object is to provide a detachable heel pad, whereby several of the heel pads may be kept by the wearer of the shoe, and as soon as the heel pad becomes worn a new heel pad may be put on in its place by the wearer without the use of any nails or the like.

Still a further object is to provide a detachable heel pad having a plate firmly secured to the fixed shoe heel, said pad having a plurality of upwardly extending projections designed to extend through said openings in said plate, and means on said plate for engaging the upwardly extending projections for securing said detachable heel pad to the plate.

With these and other objects in View our invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a sectional, perspective view of our device.

Fig. 2 shows a top or plan view of the device in engagement.

Fig. 3 shows a plan view of the detachable heel member.

Fig. 4: shows a side elevation of a shoe with our device attached thereto.

In the accompanying drawings we have used the reference numeral 10 to indicate generally a shoe. 11 is a fixed heel member.

Our device is secured to the fixed heel member by a plurality of screws 12, said screws extending into the fixed heel member 11.

The plate 13 has an upwardly extending flange 14 adapted to engage the heel member 11, and a downwardly extending flange member 15 adapted to engage the detachable heel member 16.

Resting upon the inner surface of the plate 13 is a spider member 17 having a plurality of outwardly extending resilient arms 18. At the central portion of the spider 17 is a screw-threaded portion 19.

In the plate 13, and registerin with the screw-threaded opening in the splder 19, is an opening 20. Designed to extend through the alined openings is a screw 21.

After the screw 21 is placed in engagement with the screw-threaded portion 19, the upper end at 22 is battered so as to prevent the screw from being removed from the spider, the purpose of which will be hereinafter more fully described.

The detachable heel member 16 has a central opening 23 for permitting access to the screw 21.

Secured to the detachable heel pad 16 is a plurality of screws 24, said screws being designed to extend throughthe plate 13 and project upwardly therefrom.

I The screw 2% has a series of threads or notches 25, said threads or notches being designed to coact with the resilient arms 18 for causing engagement of the detachable heel pad member with a fixed heel member of the shoe 10.

A stop 26 is provided in the plate 13 for permitting a limited amount of movement of the arms 18; V

In the practical operation of our device, the plate 13 is secured to the fixed heel member 11 by means of a plurality of screws.

The screw 21 is then rotated in a clockwise direction until the battered portion 22 becomes engaged with the screw-threaded portion of the spider, thereby causing the spider and screw to rotate in unison until the spider is prevented from rotating by means of the stop 26.

The screw 21 is then given an additional turn so as to insure a more perfect engagement between the battered portion of the screw with the spider. This position is clearly shown by the dotted lines in Fig. 2.

The detachable heel member with the upwardly projecting members is then placed on-the heel, with the upwardly projecting members extending through a plurality of openings in the plate, said openings being adapted to receive said upwardly projecting members.

The screw 21 is then turned clockwise until the outer ends of the arms 18 become engaged with the screw threads or notches provided in the upwardly projecting mem-- bers 2 1.

As soon as the arms 18 become in engage ment with the screw threads or notches of the projections, the rotation of the spider ceases.

The screw is then turned in a clockwise direction until the battered portion becomes disengaged from the screw-threaded portion of the spider, then by rotating the screw the entire central portion of the spider is pulled downwardly causing frictional engagement between the central portion of the spider 17 with the plate 13.

The arms 18 being bowed and resilient,

the frictional engagement of the central portion of the spider withthe plate, causes the arms to extend somewhat outwardly and then insures a more perfect engagement between the arms and the projections.

To remove the detachable heel pad member, the screw is turned anti-clockwise until the battered portion becomes engaged with the screw-threaded portion of the spider, and then the spider will rotate in the same direction as the screw until the spider is prevented from rotating by means of the stop.

It will be seen by causing the battered portion to become engaged with the screwthreaded portion ofthe spider 17, practically makes the spider and the screw of one piece and insures the spider to be rotated to its limit of movement both in engagement and out.

This does away with any possibility of the spider stopping; between the projections 24 and the post 26 in either of its movements into engagement or out of engagement.

It will be seen that the spider would not moveout of engagement until the battered portion of the screw was in engagement with the screw-threaded portion of the spider, and after having moved to its position of disengagement and stopped by the stop 26 would only be moved back into its position of engagement when the battered portion of the screw is in contact with the spider 17.

The detachable heel is also held in place by means of the downwardly extending flange on the plate 13. This prevents any lateral movement of the detachable heel with relation to the fixed heel plate 13, It is obvious that the screws 12 and the flange 1-1- hold the plate 13 in firmly fixed relation to the heel pad member 11.

It will be seen that our detachable heel pad 16 could be applied in a very short time to the fixed member of the heel without the necessity of a shoe repairman.

Some changes may be made in the construction and arrangement. of the various parts of our device without departing from the real spirit and intent of our invention, and it is our intention to cover by our claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

e believe we have produced a basic invention in this art andit is our purpose to claim such invention.

We claim as our invention:
